Primary hepatic angiosarcoma is a rare, aggressive tumor; composed of spindle or pleomorphic cells that line, or grow into, the lumina of pre-existing vascular spaces like sinusoids and terminal hepatic venules; with only about 200 cases diagnosed annually worldwide but it is the most common primary malignant mesenchymal tumor of the liver in adults and(More)
Protein kinase G (PknG) in Mycobacterium tuberculosis has been shown to modulate phagosome-lysosome fusion. The protein has three distinct domains, an N-terminal Trx domain, a kinase domain, and a C-terminal TPR domain. The present study extensively analyzes the roles of these domains in regulating PknG kinase activity and function. We find that the kinase(More)
mtDNA non-synonymous germ line variation (G10398A; p.A114T) has remained equivocal with least mechanistic understanding in showing an association with cancer. This has necessitated showing in-vitro how an over-expression within mitochondria of either of the variants produces higher intracellular ROS, resulting in differential anchorage dependent and(More)
We determined whether certain factor(s) secreted by multinucleated giant cells, which is of monocyte/macrophage lineage in giant cell tumor of bone (GCT), regulate the induction of matrix metalloproteinase (MMP)-9 expression in mononucleated stromal cells. Our data derived using enzyme linked immunosorbant assays (ELISAs) suggest that the GCT cells in(More)
Giant cell tumor (GCT) of bone is a progressive, potentially malignant process that destroys skeletal tissue. It consists of multinucleated giant cells, which are hypothesized to be derived from a monocyte/macrophage lineage and mononuclear stromal cells, and the precise relationship of these cells is not fully understood. Recently, we demonstrated that the(More)
This paper is a first comprehensive study on the correlated ion transport mechanisms contributing to the overall conductivity behavior in a new class of poly(ethylene oxide)-polyurethane/polyacrylonitrile (PEO-PU/PAN) semi-interpenetrating polymer networks (semi-IPNs)-salt complex polymer electrolytes. A simultaneous investigation of the electrical response(More)
Resveratrol has been shown to exhibit its anti-cancer effect through a variety of mechanisms. Here, TIGAR (TP53-Induced Glycolysis and Apoptosis Regulator) was identified as an important target of resveratrol for exhibiting ROS-dependent-consequences on apoptosis and autophagy. Resveratrol treatment decreased TIGAR protein irrespective of cell line used.(More)
Radiotherapy is the biggest force acting behind cancer treatment, yet the vast majority of patients get only modest benefit. The successive failure of targeted therapies in radiotherapy lies in the non-discriminative killing of both normal and cancer cells. However, there is still a reason for optimism due to recent advancement made in cancer biology which(More)
A penta-nucleotide microsatellite marker (CCTTT)n, in NOS2A promoter region has been associated with a variety of infectious diseases, including Tuberculosis. Most of these studies, however, are limited in justifying the association to tuberculosis through independent functional assays. The present study on 915 individuals from three geographically distinct(More)
There are approximately 240 million people across the world who are heterozygous for Beta thalassemia and 200,000 affected homozygous are born annually. Prevention is a big challenge. But the situation in India is different. Social, cultural, and religious issues are found to be closely intertwined with Beta thalassemia prevention. In spite of 10,000 annual(More)
